SIDNEY A. BEYLAND, OF NORTI? RIDGEVILLE, OHIO, ASSIGNOR TO THE GARFORD MANUFACTURING COMPANY, OF ELYRIA, OHIO, A CORPORATION OF OI-I HORN FOR AUTOMOBILES AND MOTOR-CYCLES.

Application filed October 8, 1913. Serial N 0. 794,144.

T a all whom it may concern:

) Be it known that I, SIDNEY A. BEYLAND,

a citizen of the United States, residing at North Ridgevilie, in the county of Lorain and State of Ohio, have invented certain new and useful lmprovements'in Horns for Automobiles and Motor-Cycles; and I do hereby declare the following. to bea full, clear, and exact description of my invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to automobile or 1 n0 tor-cycle horns, or warning signal deyices employed upon such vehicles, and especially to electric warning signaling devices or horns for this use. The devices of my 1nvention are also adapted to other uses where an audible signaling device is desired, such for example, as used upon motor boats for fog signals, etc.

My invention is more particularly designed for use upon motor cycles, where the horn is mounted upon the handle bars or other portion of the frame, which 1S already crowded with apparatus and accessories for use on the motor cycle; hence it is desirable to make the horn condensed and compact.

The motor cycle trade demands a small horn which will produce a loud signal, since the motor cycles travel at a rapid pace and approach an object quickly from a distance, so that it is desirable to give ample warning in order that the road may be cleared or the pedestrian warned far enough ahead to have heeded the warning before the motor cycle arrives. It is also desirable to construct the horn strong and rigid. so that it will not be injured when the motor cycle is leaned against a house, fence or other object. which is frequently done when the machine is at rest. Sometimes the horn may be struck by such object inadvertently or through ignorance on the part of the driver, with injury to the instrument.

I aim to produce a horn which will be compact. in which the apparatus will be condensed. which will be strong and durable and which will produce asignal that can be heard at a long distance away.

Otherobjects' of my invention and the" Figure 1 illustrates an embodiment of my Specification of Letters Patent.

invention, shown in section. Fig. 2 illustrates a rear elevation thereof with the back removed.

Referring now to the drawing and to the particular embodiment illustrated, at 3 I show a frame piece. which here consists of 'a plate of sheet metal cut away in the center to form anopening 4. A sonorous member such as a vibratile diaphragm 5 is associated with the frame piece and extended over the opening 4:, being exposed from the rear of the frame piece through this opening for a purpose to be described.

At 6 I show a casingfront which is perforated at 7 to form an opening for the egress of sound waves. The portions of the front casing constituting the edge of this opening may be turned up, as shown at 8, for connection with a resonator 9. which may be mounted in the opening for the transmission of the sound waves.- In the form'shown, the diaphragm is clamped between the frame piece 3 and the casing front 7 and the three parts fastened together in any Suitable means are provided for operating the sonorous member. In the. form shown electromagnetic means perform this function. Two electromagnets are shown at 13 and 14:, which are supported from the frame piece, preferably by turning up one of the portions of the frame piece, whi h constitutes the edge of the opening -t and connecting one end of the poles 16 of the magnets to the frame piece by any suitable means, such as screws 17. The ends- 16 of the poles project some little distance beyond the front end windings and are flattened off as shown at 18, presenting a flattened .sur} face to the armature. Suitable means are provided for transmitting the energy of the magnets to the diaphragm, which is here shown as an armature l9 acting as a hammer and striking upon an anvil 20 upon the diaphragm. The armature is best made rectangular in shape, its fiat under surface be- 1ng drawn to the flattened tops ot thepoles and of the magnets when they are ener the central part of the armature the anvil 20. The armature is supp from the frame by-any suitable means. such .as a spring 21 connected at one end to an edge 22 of the frame piece-and at the other to the armatureby any suitable means, such. as screws 23. In the form shown, the armature is spaced from the spring 21 by studs 24 which elevate the armature above the poles for a purpose to be described. In the form shown a switch 25 controls the circuit of the magnets 13 and 14. This switch consists of a plurality of contacts, each supported from the frame by leaf springs. The armature controls this-switch and in the form shown, I have extended one of these springs 28, as shown at 29, in order that it may be operated by the armature when vibrated to open said switch. An insulating stud connected to the armature, engages this extended end of the spring 28. Suitable means are provided for adjusting the switch, here shown as an adjusting screw 32, engaging the upper switch spring 38. The screw is supported by the bracket 34%, also supported from the frame.

' The armature SJIlIl carr in its armature, the switch springs carrying their contacts and the adjusting screw bracket carrying its adjusting screw are insulated from each other by insulation 40 and these parts are connected. together by some su' able means, such as a screw 4:1, being removable as a unit from the frame to which they are connected through a spacing member by some suitable means, such as screws 52. The terminals 5% of the-conductors leading to T the switch 25 are also carried in this re movable unitary structure, as shown in Fig. 2. A rear casing 60 is provided for covering the apparatus and is connected to the frame piece, in the form, shown, by turning up from the frame piece connecting lugs 70 to which the rear casing is connected in any suitable manner. The horn may be connected to the vehicle by any suitable means,

such as a bracket 80, which is here shown as 45 being repeated. The

apartof the frame piece.

In the operation of the horn, the circuits of the magnets are closed, including the 'switch 25, whereupon the magnets attract the armature 19, pulling it down, so that its plane remains substantially parallel to the plane of the diaphragm. When thus attracted, the armature strikes upon the anvil 20, which is here shown as a socket 90 on the diaphragm and an adjustable screw 91 fitting in the socket, the screw and socket bearing complementary threads. When the armature is thus drawn to its lower position, the striking of the diaphragm causes the same to sound a signal and the switch 25 is opened through. the engagement of the stud 30 with the end 29 of the spring 28. When thus opened,'the switch interrupts the cir cult of the magnets which become deenergized and release the armature this cycle which it is repeated depends largely upon the natural rate of vibration of the spring 21.
